Kubernetes Nginx Ingress "ingress-nginx-admission" not found

Question

I want to run a nginx ingress controller on a raspberry kubernetes.

Unfortunately I get the error message

 Events:

  Warning  FailedMount  24s (x15 over 14m)  kubelet            MountVolume.SetUp failed for volume "webhook-cert" : secret "ingress-nginx-admission" not found

there are additional logs in the github Issue . This version should be compatible with ARM CPU. I could not find any other information on setting up the this ingress controller on raspberry Pis.

Not very sure what exactly happened on your device. But I got a very similar issue. The solution may be helpful.

If you have tried multiple times to destroy the cluster, by kubeadm reset , without removing cni0 device, ingress-nginx-admission pod won't be able to get created due to failure to connect API server.

Either deleting cni0 device or simply restarting Pi device should remove such device successfully.

I would also check whether the following directories and files are deleted after running kubeadm reset

sudo rm -fr /etc/kubernetes/; sudo rm -fr /var/lib/etcd; sudo rm -rf /var/lib/cni/
sudo rm -fr /etc/cni/net.d
